I mean the AD just have summerset isles when the empire has cyrodill, skyrim, morrowind, etc. and the AD managed to destroy Cyrodill and got the empire to surrender.

They have Valenwood and Elsweyr as well, and the Empire was caught off guard, and they chose to ignore the signs of Cthulhu's rising.

edit: The Empire also doesn't have Morrowind, and Cyrodiil while severely damaged wasn't destroyed.

Hmmm I don't ever recall them mentioning Wood Elves or Khajiits fighting in the Great War. It's likely the Wood Elves might have fought but Elseweyr is only a couple client states so their participation is likely to less than the others.

The Aldmeri Dominion consists of Summerset, Valenwood. and Elsweyr.

1. They did not destroy Cyrodiil and the Empire didn't surrender.

2. As stated, they also hold Valenwood and run the puppet governments in Elsweyr.

3. They had incredibly powerful mages who were possibly thousands of years old.

4. The Empire held Cyrodiil, Skyrim, High Rock, Hammerfell, and nominally they held whatever was left of Morrowind. However, only Cyrodiil, Skyrim, and High Rock were actually peaceful and prosperous before the Great War.

If they have Valenwood and Elsweyr, why do you only see high elves fight.

Because those are Thalmor, not Dominion forces.

Valenwwod and Elsweyr are what's keeping any navy force from even trying to do a suicide run.

Aldmeri forces are mentioned. Not Altmeri. Though the Altmer did likely form the majority. The Bosmer and Khajiit are being saved for later when needed for all-out war.

They destroyed some cities of cyrodill and severly damaged the imperial city. "The empire didn't surrender." White-Gold Concordat?

We don't know that to be true, and it was mentioned that they used all available forces for the war.

And yet we hear virtually nothing explicitly about the Bosmer or Khajiit. It's all very much vague. It's clear the Altmer were the majority.

I'd be more worried about Elsweyr at the moment. Should they actually fully support the Dominion and deploy the Senche-Raht or Cathay-Rahts into the frontlines then the the rest of Tamriel is screwed.

Still the Wild Hunt is unarguably the most dangerous "weapon" the Dominion has, though if not done right could be as dangerous to the Dominion as it would be to their enemies. If I was planning a war with the Thalmor then getting Elsweyr away from their influence takes priority. Valenwood would come next.

I don't recall them destroying any cities. They did capture Bravil, Leyawiin, Skingrad, Anvil, and Kvatch. The Imperial City was sacked but not destroyed. The White-Gold Concordat was not a surrender considering the Dominion had failed in their goal of completely destroying the Empire.

Majority, probably. Probably would be the case no matter what. The war in general was quite vague.

I don't think the Khajiit have any intention of fully supporting the Dominion in their wars. Maybe they would auxiliary troops or something of the like. There is no evidence of them fighting in the Great War. The only role they played was allowing the Domnion to flank the Imperial defenses on the Valenwood border, though to what extent the Khajiit could have even resisted this movement is debatable.

I hate using real world examples, but the Bosmer fighting in the Great War seem to me like the Romanians fighting in World War 2. Sure, they were technically allied with Germany, but they didnt exactly have a choice in the matter.

I wouldn't say that. Cathey Raht's population wouldn't be very big considering their birth relies on the phase of the moon they were born under, and the bosmer have fought them before without the wild hunt being necessary besides in that one particular war. Strong, yes, but not enough to screw all of tamriel. Not unless they could get an army of the Catheys.

Their primary goal was to enforce a couple rules on the empire which they did when the Empire came with the WGC thus making the Dominion the victors of the Great War.

Dude the Bosmer did invoke the wild hunt when they fought the Khajiits in the Five Year war because of the Senche and Cathay, and I did mention the Wild Hunt being the most effective weapon for the Dominion. However it's also the most riskiest one.

No, their goal became the complete overthrow of the Empire, which they failed to achieve, and then they had two of their large armies annihilated.

I know they did. I said they fought before besides that particular battle without needing it.

No, the whole war was started because Mede rejected the ultimatum presented to him by the Thalmor ambassador. Their only real failure was in Hammerfell.

Which one?

Was it? They may not have taken it, but they separated it from the Empire. May come to bite them in the but if Skyrim can pull an alliance, but still. That's an if. I wouldn't call it a failure per say.

I still enjoy the theory that the Dominion is being controlled by Jyggalag...

it may not be the post probable theory out there, but there is a small amount of ground that could support that theory...

I know why the war was started. Read http://uesp.net/wiki/Lore:The_Great_War_(book).

"It appears now that the initial Aldmeri objective was in fact the conquest of Hammerfell, and that the invasion of Cyrodiil was intended only to pin down the Imperial legions while Hammerfell was overrun. However, the surprising initial success of Lord Naarifin's attack led the Thalmor to believe that the Empire was weaker than they had thought. The capture of the Imperial City itself and the complete overthrow of the Empire thus became their primary objective of the next two years."

So the Dominion failed at all of their goals. You need to understand this: once the Empire refused the ultimatum, the Thalmor decided that they were going to simply take Hammerfell's coast by force. Then, they decided to attempt to destroy the Empire. This was their goal. The ultimatum's demands were out the window once hostilities began. The fact that the Empire was able to barter a treaty with the Thalmor after destroying a good portion of their forces makes it a truce, not a defeat.
